Do you think bikes are popular in your country?
Puntuación: 45.0Sugerencia: Answer directly, then support your opinion with a clear reason or example. Say "many different types of bikes" instead of "a lot of grades of bikes," and avoid repeating "people like" by combining your ideas. Remember to use "a lot of" before a plural noun.
Ejemplo: Yes, bikes are quite popular in my country. These days, people can choose from many different types, and cycling is a popular way to exercise or explore the countryside.

The question asks about the past, so the verbs should be in the past tense: use didn't have instead of don't have and had instead of have. When describing a past state, use was, as in I was a child.
× No, I don't have bike when I was child at that time I have a bicycle.
✓ No, I didn't have a bike when I was a child. At that time, I had a bicycle.
Bike and child are singular countable nouns, so they need an article in these phrases. Use a bike and a child.
× Yes, bikes are popular in my country because I can see nowadays people have lot of grades of bikes.
✓ Yes, bikes are popular in my country because I can see that nowadays people have a lot of grades of bikes.
The quantifier phrase is a lot of, not lot of. Include a before lot. Adding that after see also makes the clause boundary clearer, though it is optional.
× People like to travel, people like to go for rides.
✓ People like to travel, and they like to go for rides.
The original joins two independent clauses with only a comma, creating a comma splice. Join them with a coordinating conjunction such as and, or use a semicolon or a full stop.
